๐ค AI Enhancement
๐ง Intelligent Process Analysis AI Powered
Let AI analyze your plant data and provide optimization recommendations
Based on current F/M ratio and MLSS levels, consider increasing RAS rate by 8-12% to improve settling and reduce SVI.
DO levels are consistently above setpoint. Reducing blower output by 15% during 2AM-6AM could save approximately $2,400/month.
SVI trend indicates potential filamentous bulking in 7-10 days. Consider implementing chlorination or nutrient adjustment.
